I've played two (technically three) Persona games. One of them is a lock for a slot in my top ten games of all time, and the other would rate pretty highly as well.
I've played three (main series) Final Fantasy games, including the two that seem to be lauded as the best in the series. I didn't even enjoy either of those enough to finish them, and while the other one was alright, I don't think it'd even be in a *top 50* conversation.
tl;dr: Persona, and it's *not* close~
